摘要: 报告1例利用部分脱矿自体牙本质颗粒(partially demineralized autogenous dentin matrix,PDADM)联合自体血液浓缩物富血小板纤维蛋白(Platelet-Rich Fibrin, PRF),为纵裂的上颌第一磨牙进行拔牙位点保存术,术后3个月、6个月、15个月的CBCT显示骨量维持效果明显。组织学切片可见牙本质颗粒周围有大量新形成的编织骨。

关键词: 位点保存, 牙本质颗粒, 富血小板纤维蛋白

Abstract: Partially demineralized autologous dentin matrix (PDADM) combined with autologous blood concentrate platelet-rich fibrin (PRF) was used for alveolar ridge preservation of vertically fractured upper first molar. After 3 months, 6 months, and 15 months, CBCT investigation revealed significant bone volume maintenance. Biopsy displayed a large amount of newly formed woven bone around dentine particles.

Key words: site preservation, dentin particles, platelet-rich fibrin
